[0018] The swingable assembly 3 includes a swingable member 31 and a connecting member 32, and the swingable member 31 is pivotally connected to one of two ends of the slidable member 2 and one of two ends of the connecting member 32.

[0019] The first adjusting assembly 4 is attached to the main body 1 at the second end and optionally movable relative to the main body 1 along the linear direction. The first adjusting assembly 4 is adapted for the other of the two ends of the connecting member 32 to abut against optionally.

[0020] The second adjusting assembly 5 is attached to the main body 1 and optionally movable relative to the main body 1 along the linear direction.

[0021] The clamp assembly 6 includes a first clamp portion 61 and a second clamp portion 62, the first clamp portion 61 and the second clamp portion 62 are aligned along the linear direction, the first clamp portion 61 is comovably disposed on the slidable member 2, and the second clamp portion 62 is comovably disposed on the other of the two ends of the second adjusting assembly 5. In this embodiment, one of two ends of the slidable member 2 away from the swingable member 31 is integrally connected to the first clamp portion 61. A maximum distance between the first clamping portion 61 and the second clamping portion 62 is adjustable by moving the second adjusting assembly 5 along the linear direction.

[0022] When the swingable member 31 swings toward the main body 1, the swingable member 31 pushes the slidable member 2 toward the second clamp portion 62 along the linear direction, and the first and second clamp portions 61, 62 can clamp an object (as shown in FIG. 4); and when the swingable member 31 swings away from the main body 1, the swingable member 31 pulls the slidable member 2 to move away from the second clamp portion 62 along the linear direction to release the object (as shown in FIG. 3).

[0023] Furthermore, in this embodiment, the first adjustment assembly 4 includes a first threaded rod 41, and the first threaded rod 41 is screwed with the main body 1 along the linear direction and abuts against the connecting member 32. Through screwing the first threaded rod 41, the first threaded rod 41 moves along the linear direction to adjust positions of the connecting member 32 and the swingable member 31 relative to the main body 1 so as to adjust the positions of the slidable member 2 and the first clamp portion 61 comovable with the slidable member 2 relative to the main body 1.

[0024] Specifically, in this embodiment, the second adjustment assembly 5 includes a rod member 51 and an adjusting member 52, the adjusting member 52 is pivotally connected to the main body 1, the rod member 51 has a first toothed portion 511, the adjusting member 52 has a second toothed portion 521, the second toothed portion 521 normally abuts toward the first toothed portion 511, and the second clamp portion 62 is comovably disposed on the rod member 51. More specifically, the main body 1 further has a position-restricting member 11 fixedly disposed thereon, the rod member 51 is slidably connected to the position-restricting member 11, a pivot axle 55 is disposed through the adjusting member 52 and the position-restricting member 11, a spring 53 elastically abuts against and between the position-restricting member 11 and one of two ends of the adjusting member 52 which is away from the second toothed portion 521, and the pivot axle 55 is located between the second toothed portion 521 and the spring 53 so that the two ends of the adjusting member 52 are in a seesaw state and swingable relative to each other.

[0025] Specifically, in this embodiment, the position-restricting member 11 is a rectangular tube, a side of the position-restricting member 11 further has a receiving groove 111, the adjusting member 52 is pivotally arranged within the receiving groove 111, when the second toothed portion 521 abuts against the first toothed portion 511, one of the two ends of the adjusting member 52 which is away from the second toothed portion 521 extends beyond the receiving groove 111, if a user wants to adjust relative positions of the rod member 51 and the position-restricting member 11, the user only needs to press one of the two ends of the adjusting member 52 away from the second toothed portion 521 downward toward the receiving groove 111, the second toothed portion 521 which is at the other of the two ends of the adjusting member 52 upturns and is detached from the first toothed portion 511, and the rod member 51 can slide freely relative to the position-restricting member 11 so as to adjust the relative positions of the rod member 51 and the position-restricting member 11.

[0026] Therefore, through adjusting the first adjustment assembly 4 and the second adjustment assembly 5, the user can adjust, in advance, an initial distance between the first clamp portion 61 and the second clamp portion 62 (that is, when the swingable member 31 and the main body 1 swing toward each other) according to a size of the object (as shown in FIG. 5) so as to prevent the user from hand sore due to opening or closing the first and second clamp portions 61, 62 which are in a great distance.

[0027] In this embodiment, the main body 1 is reversed U-shaped board and defines a receiving space 12, the slidable member 2 and the position-restricting member 11 are arranged in the receiving space 12, one of two ends of the main body 1 away from the first clamp portion 61 further has a narrowed section 13, and one of two ends of the connecting member 32 away from the first clamp portion 61 is positioned in the narrowed section 13.

[0028] Preferably, the pliers includes an elastic member 72, two ends of the elastic member 72 are respectively arranged between a groove 112 of the position-restricting member 11 (in this embodiment, two ends of the elastic member 72 hook on the groove 112) and the slidable member 2 so that the slidable member 2 has a tendency to move away from the second clamp portion 62; therefore, the user only needs to control the first clamp portion 61 and the second clamp portion 62 to approach each other.

[0029] In this embodiment, the rod member 51 further has a position-restricting slot 512 which extends along the linear direction (as shown in FIG. 6), a pin member 54 is disposed through the position-restricting member 11 and abuts against the position-restricting slot 512, and through the pin member 54 cooperating with the position-restricting slot 512, the rod member 51 can be slidably connected to the position-restricting member 11 but cannot be detached from the position-restricting member 11.

[0030] It is to be noted that the pliers further includes a toggling member 71, the swingable member 31 and the slidable member 2 are pivotally connected to a first pivot portion 81, the swingable member 31 and the connecting member 32 are pivotally connected to a second pivot portion 82, one of two ends of the toggling member 71 and the swingable member 31 are pivotally connected to a third pivot portion 83, the second pivot portion 82 is located between the first pivot portion 81 and the third pivot portion 83, one of the two ends of the toggling member 71 away from the third pivot portion 83 is a free end, when the swingable member 31 swings toward the main body 1, a middle section 711 of the toggling member 71 between the free end and the third pivot portion 83 abuts against a protrusion 321 of the connecting member 32, when the free end of the toggling member 71 is pressed and swings toward the main body 1, the middle section 711 serves as a fulcrum of the toggling member 71, and the third pivot portion 83 drives the swingable member 31 to swing away from the main body 1 so that the user does not need to change the way s/he grips to control the first and second clamp portions 61, 62 to move away from each other.

[0031] Given the above, in the pliers, through adjusting the first and second adjustment assemblies, the user can adjust, in advance, the initial distance between the first clamp portion and the second clamp portion (that is, when the swingable member and the main body swing toward each other) according to the size of the object so as to prevent the user from hand sore due to opening or closing the first and second clamp portions which are in a great distance.

[0032] While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
